| Research Abstract |
Magnetohydrodynamic(MHD) turbulence in space plasma is often found to have very large amplitude, suggesting that nonlinear wave-wave interaction is in progress. In order to examine such turbulence using multiple spacecraft data, methods of evaluating higher order statistics using a small number of data points are developed, based on the so-called Capon' s method that is usually used for the determination of the wave number spectrum.
